[종래 기술]BACKGROUND ART [0002]
자동차의 등화장치는 그 기능면에서 볼 때 전조등, 안개등, 후진등과 같은 조명을 목적으로 한 것과 방향지시등, 제동등, 후미등, 차폭등, 번호판등, 비상등과 같은 자기 차의 주행상태를 알리는 것을 목적으로 하는 것으로 나뉘어진다. 상기한 신호기능을 가진 램프들은 제약된 설치공간을 고려하여 구조상 일체로 된 경우가 많으며 이러한 램프를 콤비네이션 램프라고 한다.The lighting system of a car is intended to illuminate headlights, fog lights, back lights, etc., and to inform the driving conditions of its own vehicles such as turn signals, brake lights, tail lights, . The lamps having the above-mentioned signal function are often structurally integrated in consideration of the limited installation space, and these lamps are called combination lamps.
후미등(tail lamp)은 야간에 주행하거나 정지하고 있을 때 차의 존재를 뒤차에 알리는 등으로서 구조는 후미등만으로 사용하는 단독식과 제동등과 겸용으로 사용하는 겸용식이 있으며, 렌즈는 적색으로 착색되어 있고 전조등 회로에 접속되어 전조등과 연동하여 동작한다.The tail lamp is a combination of a stand-alone type used as a tail light only and a dual-use type as a brake light. The lens is colored in red, and the tail lamp And operates in conjunction with the headlight.
한편 브레이크등은 브레이크 페달을 밟았을 때 뒷차에 제동을 알리는 램프로서, 후미등과 같이 단독식과 겸용식이 있으며 적색의 렌즈를 사용한다. 이 경우 겸용식에 있어서는 후미등과 중심광도가 적어도 2배 이상 차이가 나야 한다.On the other hand, the brake lamp is a lamp that notifies the rear car of braking when the brake pedal is stepped on. It has a single type and a combination type like a tail lamp and uses a red lens. In this case, the combination of the tail light and the center luminous intensity should be at least two times greater than the combined luminous intensity.
브레이크등에 대한 작동은 제1도에 도시된 바와같이 브레이크 페달의 으로드에 연결되어 브레이크 페달을 밟는 것에 따라 스위치 접점이 닫히는 기계식 스위치 또는 마스터 실린더 내의 유압상승에 연동하여 접점이 작동되는 유압식 스위치(1)를 사용하여 브레이크등(3)을 점등시키고 있다.The operation of the brake or the like is performed by a mechanical switch that is connected to the rod of the brake pedal and depresses the brake pedal to close the switch contact as shown in FIG. 1, or a hydraulic switch 1 ) Is used to turn on the brake lamp (3).
또한 비상등은 비상시나 주정차시 또는 고속 주행중에 급감속을 하는 경우 푸시 버튼식 스위치를 작동시킴에 의해 방향 지시 등을 소정 주기로 점멸 구동시킨다.In addition, when the emergency light suddenly decelerates during an emergency, a pneumatic vehicle or a high-speed driving, the push-button type switch is operated to drive the direction indication or the like to blink in a predetermined cycle.
[발명이 이루고자 하는 기술적 과제][Technical Problem]
그런데 고속주행, 특히 눈/우천시의 고속 주행 상태 또는 급경사 내리막길을 주행하는 경우의 감속이 필요한 경우는 브레이크 페달을 작동시키는 것보다 엔진 브레이크를 사용하는 것이 사고의 위험을 줄일 수 있는 것으로 알려져 있다. 그러나 이러한 감속의 경우 브레이크등은 작동되진 않으므로 추속차량에 의해 추돌사고가 발생할 가능성이 크며 이 경우 비상등을 켜주는 것은 매우 번거로운 일이며 순간적으로 발생할 수 도 있기 때문에 적절한 순간에 이를 실행하는 것은 쉬운 일이 아니었다.However, it is known that the use of the engine brake may reduce the risk of accidents when the vehicle is traveling at a high speed, particularly in the case of snow / rain, or when deceleration is required when traveling on a steep downhill road. However, in the case of such a deceleration, the brakes, etc., are not operated. Therefore, there is a high possibility that a collision accident occurs due to a stalled vehicle. In such a case, turning on the emergency light is very troublesome and may occur instantaneously. It was not.
본 발명은 이러한 종래기술의 문제점을 감안하여 안출된 것으로, 그 목적은 엔진 브레이크를 사용할 경우 차속과 RPM의 변도에 따라 급감속을 판단하여 브레이크등과 비상등을 작동시키에 의해 후속차량에 의한 추돌사고를 방지할 수 있는 속도와 RPM 감응형 감속 주행 경고장치를 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a vehicle collision detection system, And an RPM-sensitive deceleration warning device capable of preventing an accident.
[발명의 구성 및 작용][Structure and operation of the invention]
상기한 목적을 달성하기 위하여, 본 발명은 차량의 차속신호를 발생하는 차속센서와, 엔진의 RPM 값을 발생하는 RPM 감지센서와, 주기적으로 차속신호 또는 RPM 값을 받아들여 기억되어 있는 바로 종전의 차속신호 또는 RPM값과 비교하여 속도 감소율 또는 RPM의 증가율이 소정의 설정값 이하인 경우에는 제1제어신호를 발생하고, 소정의 설정값 이상인 경우에는 제2제어신호를 발생하는 제어수단과, 상기 제1제어신호에 응답하여 좌/우 브레이크등을 작동시키기 위한 브레이크등 릴레이와, 상기 제2제어신호에 응답하여 비상등을 작동시키시 위한 플레셔 유니트로 구성되는 것을 특징으로 하는 속도와 RPM 감응형 감속 주행 경고장치를 제공한다.In order to accomplish the above object, the present invention provides a vehicle speed sensor comprising: a vehicle speed sensor for generating a vehicle speed signal of a vehicle; an RPM sensor for generating an RPM value of the engine; A control means for generating a first control signal when the speed reduction rate or the rate of increase of the RPM is less than a predetermined set value by comparing the vehicle speed signal or the RPM value and generating a second control signal when the rate is lower than a predetermined set value, And a flare unit for activating an emergency light in response to the second control signal, wherein the control unit is configured to control the speed and the RPM responsive deceleration driving warning Device.
상기한 바와같이 본 발명에서는 브레이크 폐달을 사용하지 않고 엔진 브레이크를 사용하여 급감속을 하는 경우 차속과 RPM의 변화를 검출하여 변화의 정도에 따라 초기에는 브레이크등만을 작동시키고, 속도 감소율이 소정값 이상으로 되는 경우에는 비상등을 작동시킨다. 따라서 후속차량의 운전자가 선행차량의 감속운전을 인지하여 안전운전을 하게되므로 추돌사고를 예방할 수 있게 된다.As described above, in the present invention, when the engine brake is used to rapidly decelerate without using the brake pedal, the change of the vehicle speed and RPM is detected, and only the brake or the like is initially operated depending on the degree of change. The emergency light is activated. Therefore, the driver of the succeeding vehicle recognizes the decelerating operation of the preceding vehicle and performs the safe driving, so that the collision accident can be prevented.
[실시예][Example]
이하에 상기한 본 발명을 바람직한 실시에가 도시된 첨부도면을 참고하여 더욱 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
첨부된 제2도는 본 발명에 따른 속도와 RPM 감응형 감속 주행 경고장치에 대한 제어 회로도로서, 이에 도시된 바와같아 본 발명의 감속 주행 경고 장치는 마아크로프로세서(CPU)로 구성될 수 있는 제어부(11)의 입력측에 차량의 차속신호를 발생하는 차속센서(13)와, 엔진의 분당회전 속도, 즉 RPM 값을 발생하는 RPM 감지센서(15)가 연결되어 있다.FIG. 2 is a control circuit diagram of a speed and RPM-sensitive slow running warning device according to the present invention, as shown in FIG. 2; FIG. 2 is a block diagram of a deceleration running warning device according to an embodiment of the present invention; A vehicle speed sensor 13 for generating a vehicle speed signal of the vehicle at the input side of the engine 11 and an RPM detection sensor 15 for generating the RPM value per minute of the engine.
또한 제어부(11)의 출력측에는 좌/우 브레이크등(19)을 작동시키기 위한 브레이크등 릴레이(17)와, 비상등(25)을 작동시키기 위한 플레셔 유니트(23)가 연결되어 있으며, 상기 브레이크등 릴레이(17)의 가동접점(17A)과 브레이크등(19) 사이의 접속점에는 브레이크 폐달 스위치(21)의 일측 단자가 연결되어 있다.A relay 17 such as a brake for operating the left / right brake light 19 and a fresco unit 23 for operating the emergency light 25 are connected to the output side of the control unit 11, One end of the brake pedal switch 21 is connected to a connection point between the movable contact 17A of the brake pedal 17 and the brake pedal 19.
상기와 같이 구성된 본 발명의 감속 주행 경고장치의 작용을 이하에 상세하게 설명한다.The operation of the deceleration running warning device of the present invention constructed as above will be described in detail below.
운전자가 고속주행 또는 급경사 하강도로를 주행중에 브레이크 폐달을 사용하지 않고 엔진 브레이크를 사용하여, 즉 변속기어를 5단에서 1단으로 변속하여 급감속이 이루어진 경우 브레이크 폐달 스위치(21)는 작동하지 않는다.The brake pendulum switch 21 does not operate when the driver uses the engine brake without using the brake pedal during high-speed running or on the steep descent road, that is, when the speed change is made by shifting the transmission from the fifth stage to the first stage.
그러나 이 경우 차속센서(13)로부터 현재의 차속신호가 입력되고 RPM 감지센서(15)로부터 현재의 RPM 신호가 입력된다.In this case, however, the current vehicle speed signal is input from the vehicle speed sensor 13 and the current RPM signal is input from the RPM detection sensor 15. [
이에 응답하여 제어부(11)는 주기적으로 입력되는 현재의 차속과 RPM을 각각 종전의 차속 및 RPM과 비교하여 감속 여부를 판단한다.In response, the control unit 11 compares the current vehicle speed and the RPM, which are periodically input, with the previous vehicle speed and the RPM to determine whether to decelerate.
판단결과 엔진브레이크 작동에 따라 차속이 감소하고 RPM이 증가한 경우 제어부(11)는 제1제어신호를 발생하여 브레이크등 릴레이(17)를 온시킴에 의해 브레이크등(19)을 점등시킨다.If the vehicle speed decreases and the RPM increases according to the engine brake operation, the control unit 11 generates the first control signal to turn on the brake light relay 17 to turn on the brake light 19.
그후 차속의 감소율과 RPM의 증가율이 소정의 설정값 이상으로 되는 경우 제어부(11)는 제2제어신호를 발생하여 플레셔 유니트(23)를 작동시킨다. 그 결과 비상등(25)이 소정 주기로 점멸구동하게 된다.Thereafter, when the reduction rate of the vehicle speed and the rate of increase of the RPM become equal to or greater than a predetermined set value, the control unit 11 generates the second control signal to operate the fuser unit 23. [ As a result, the emergency light 25 is blinkingly driven at a predetermined cycle.
상기 제어부(11)는 상기와 같이 차속센서(13)와 RPM 감지센서(15)로부터 발생된 신호값을 주기적으로 셈플링하여 받아들인 후 기억되어 있는 종전의 데이터값과 비료하고, 종전의 데이터값을 새로운 데이터값으로 갱신시킨다.The control unit 11 periodically samples and receives the signal values generated from the vehicle speed sensor 13 and the RPM detection sensor 15 as described above and then manages the stored data values as the previous data values, To a new data value.
한편 차량의 주행속도가 다시 증가하게 되는 경우 제어부(11)는 상기 차속센서(13)와 RPM 감지센서(15)로부터의 입력신호를 판단하여 상기 제1 및 제2제어신호의 발생을 중지한다. 그 결과 브레이크등(19)과 비상등(25)은 소등된다.The control unit 11 determines the input signals from the vehicle speed sensor 13 and the RPM detection sensor 15 and stops the generation of the first and second control signals. As a result, the brake light 19 and the emergency light 25 are turned off.
더욱이 본 발명에서는 상기 제어부(11)는 내부의 미분기를 이용하여 입력되는 속도신호와 RPM 값을 미분하여 속도 감소율과 RPM의 증가율을 구할 수도 있다.Further, in the present invention, the controller 11 can differentiate the speed signal and the RPM value input by using the internal differentiator to obtain the speed reduction rate and the rate of increase of the RPM.
